Hi Enjoykin,
Ferrite cores in the image above can be found or purchased from? You can tell measurements Kohm / cm on a clean surface of the core. . . this is just a little comparison, the core that I'm there. . .

Thanks

Hi havuhung. 

Ferrite cores can't be purchased from nowhere !! It's old П-type Soviet Ferrite.

Measurements absolutely aren't important to you. Every Ferrite core will work when is perfectly tunned. Internal structure of Ferrite is what is really important - not dimensions.

Try old Ferrites from old TV CRT monitors, old TVs,, from old PS or microwave ovens. !!

OK, so I found some heavy Litz wire on an inductor from an old CRT TV set, and so I used it to rewind my "primary". So that takes care of that.

And... it did make some difference in the waveforms. I get higher voltage peaks now, and some little differences in shape and frequency. I also discovered something very significant... and I'm now able to reproduce the performance in the video, keeping the LEDs lit with no battery connected to the circuit.

No tiny wires, no concealed battery connected to the circuit, none of that. But the Objekt is NOT a self-runner. There is a secret...

Hi TK. I guess in your case you are using something like a tesla coil to wirelessly power it?
All the best..

@Enjoykin:

Are you absolutely sure about that?

It is definitely true that standard markings for ceramic capacitors use the last digit as the exponent.
So capacitors marked "330" are 33 pF.
That is, 33 x 10⁰ = 33 pF
"331" means 330 pF, that is 33 x 10¹ = 330 pF
"332" is 3.3 nanoFarad, that is 33 x 10² = 3300 pf or 3.3 nF, etc.

Do you have any evidence for the "330 pF" value of those capacitors?

Hi TinselKoala

I know perfectly markings of Russian and Americans standars of electronic components.

About cap.value. It is strictly dependant on particular ferrite. If you tune cap.value exactly at Ferro-resonant points of one ferrite - it will not work on other ferrite unless you find exactly right value.
Put variable capacitor/s in parallel to fixed one and adjust untill you get self-runner. If you know electronics excellent you can do the same with voltage controlled capacitors - varators.

About Litz wire. Make own litz wire. all you need is Electric Screwdriver and bunch of enamelled magnet wires - for example 0.25 mm².

conclusion:
As i said in my earlier posts - circuits are very simple but extremely difficult at tunning. Ferrite need precise PCM modulation both LF and HF freq. with right ammount od Duty Cycle for each. All these parameters need to be found experimentally. Because that i clearly said everybody - don't try this builds if you haven't 2 channel oscillograf and 2 signal generators. And lot of nervs.

Hi Enjoykin. What do you mean by 'NF'? HF is usually used for 'high frequency', but I don't
know what you mean by 'NF'.
All the best...
